SOUND-PRODUCING- DEVICE.

Application filed March '7, 1922, Serial This invention relates to sound producing devices, particularly such as are adapted for use in connection with or for lnsertlon 1n dolls or other toys. I

The object of my improvements is to provide a device of the class described, slmple in construction, having few parts easily assembled and, when assembled, having small liability to derangement. Other objects Wlll. appear later herein.

In the drawings accompanying this specification there is illustrated one embodiment of my invention and which is at present the preferred embodiment thereof, for use in the bodies of dolls wherein the sound required is in imitation of the cry of a child and of an intermittent or variable nature. For other toys orother uses, the device may be modified to meet particular environments and requirements, all within the scope of my invention.

Figure 1 is a vertical sectional elevation on line 11 of Fig. 2. Fig. 2 is an end elevation looking from the right of F 1g. 1. Fig. 3 is a plan view of the bellows element of the device. Fig. 4 is a view similar to that of Fig. 2, showing the operation of the device. Fig. 5 is a sectional elevation, s1m1- lar to that of Fig. 1, showing a modified form of my improvements. Fig. 6 is a fragmentary front end view, corresponding with Fig. 5. 7 is a front end view, similar to that of Fig. 6, showing a step in the operation of the device. Fig. 8 is a fragmentary sectional elevation, similar to Fig. 5, showing a further modification of arrangement. All the figures of the drawings are to one scale.

Referring now particularly to Figs. 1 to 4. inclusive, my improvements comprise a bellows 8, preferably of ordinary character with two rigid walls 2, 1, articulated along their adjacent ends 2*, 1, and having the usual flexible side Walls, as 7, and end wall 8. One wall, as 41, of said bellows may be secured to a fixed portion of the device, as wall 9 of a containing case 10. Said case preferably comprises four walls 9, 11, 12 and 13, arranged to form a rectangular box, and end wall. 14; closing in one end of said box. The other end of said box or case is preferably provided with a covering 15 of No. 541,757. itencwednpril 28, 1925.

as the movable wall, is preferably of metal and preferably carries integral there-with reed box 16 having the usual reed 17. Said metal 'wall 2 and reed box 16 constitute a weight sufficient to actuate the bellows when the device is moved from inoperative to operative posit-ion. Said reed box communicates with sound chamber 19 by passage 18. Said sound chamber has the usual nasal vent? 19 and in its right hand end, Fig. 1, vent 20, preferably of circular form, from which the sound proceeds, when permitted, and as governed in timing by means presently to be described. Adjacent the path of vent 20, downwardly from the position of Fig. 1, as the bellows movable wall closes, is wall 21 extending across and from top to bottom of the otherwise open end of case 10. Said wall 21 is of peculiar vertical profile, as shown in said Fig. '1, in that one or more portions of said wall, in number corresponding with the number of sound emissions desired during the closing of the bellows, are curved inwardly toward and into the path 22 of vent 20. The major portion of wall 21 is preferably of rigid sheet material and ma be provided with openings, as 23, 2 1, there through at those portions which project into the path of vent 20. Said openings are covered with flexible sheet material 25, such as rubber, and in the path of said vent, slits 26, 27 are cut through said sheet 25. Said slits are preferably vertical, and normally closed. Said slitted flexible sheet is in the nature of a gate or gates and which slits when open provide a passage for the sound emitted through vent 20.

The operation of this embodiment of my improved device will be understood from the showing of Fig. 1, wherein vent 20 is in engagement with that portion of flexible sheet 25, over opening 23, and has forced forwardly and apart the opposite edges of slit 26, thereby providing a free passage for the air and the sound caused thereby from said vent 20 to without said wall 21 when said sound is audible. As said vent descends further, it will .pass from engagementwith that portion of flexible sheet 25 over opening 23, whereupon slit 26 will close to the position of Fig. 2, thus shutting. off the free passage of air and audible sound to the outside, and vent 20 will presently pass into engagement with that portion of flexible sheet 25 over opening 24.- and force forwardly and apart the opposite edges of slit 27, thereby providing a passage for the air and sound from said vent, all as'just described in relation to slit 26, any sound emitted during the passage of vent 20 from opening 28 to opening 24: being confined and inaudible. Then upon the further descent of said vent, slit 27 will close. Auxiliary vent 19* allows slow ingress or egress of air during the times when vent 20 may be closed while passing into or out of engagement with said gates.

In the modification otFigs. and 6, vent is preferably of rectangular contour and of a width nearly equal to that ofbellows movable wall 2. End walls 28, 29of the vent nose are preferably curved outwardly, so that when gate of flexible sheet material, is secured thereto and to the upperand lower edges of the vent nose to cover said vent, said gate has an approximately cylindrical contour. Lying centrally said cylindrical contour and transverse said movable wall 2 is slit 26 of elongated lozenge shape, normally open at its transverse mid-portion. Adjacent the path of vent nose 20, downwardly from the position of Fig. 5, as the bellows movable wall closes, is gate operating means for closing said slit 26. Said means may comprise a pieceof wire conveniently attached at top and bottom, or either, to case 10. Said wire has a vertical profile, Fig. 5, very similar to the profile of wall 21 of Fig. 1, having portions 23, 24 projecting into the path of gate 25, whereby, when saidgate engages one o f those portions, as 2 1*, seedotted position Fig. 5, also Fig. 7, the edges of lozenge shapedv slit 26 are forced together, thereby closing gate-25 against the emission of sound. i

The modification. of Fig. 8 is very similar to that of Figs. 5, 6 and 7, except that gate 25 of F 8 is preferably in a plane rather.

than curved cylindrically outwardly, as in Figs. 5, 6 and 7, and slit 26 is normally closed, as in the dotted posit-ion of Fig. 8, the edges thereof being forcedinwardly and apart, see Fig. 8, as said gate encounters an inwardly projecting portion of gate operating. wire 30.

The operation of the modification shown in Figs. 5, 6, and 7 is similar to that described in connection withthe showing of Figs. 1, 2, 3 and 4, except that in said modification the gate is mounted on the movable member instead of on the fixed member, and intermission of audible sound is'caused by the closing of said gate duringlts engagement with: the projectingv portions of the fixed member.

In the operation of the modification shown in Fig. 8 the gate'is normally'closed and intermittent sound is emitted as said gate comes into engagement with the proauxiliary vent 19 allowing the bellows to continue its movement when said gate is closed.
